Super Light Magnesium Oxide (0.10–0.13 gm/ml) is a highly porous, ultra-low bulk density grade of MgO known for its excellent reactivity and fine particle size. It is widely used in pharmaceuticals, food, cosmetics, ceramics, rubber, plastics, and chemical industries as an antacid, acid scavenger, pH regulator, filler, and stabilizer. Its lightweight nature ensures easy blending, high absorption, and effective performance across applications.
